A comparison of two brands of flashlights used by airsoftes in this review by the Airsoft Headquarters to help you decide which meets your requirements... "Quick note that both of these brands of flashlights are REALLY good lights. While some people are going to be brand loyal I do think that it only fair that we take a deep dive together on the build, performance, and attributes of each flashlight. The flashlights and accessories have been bought by myself, no sponsorships or help in getting anything I discuss so it can be as unbiased as possible. And all the information provided is based on research and personal experiences."
